Application le February l, 3.9091. Serial 'o. 116,470.

have invented eertein new and nsefnl lma valve which will not require any peeking around the stem end is designed es an nnprovernent over the valve shown and described in e. certain pending application filedy by ine July ist7 1907, Serial No. 381.613.

ln the accompanying drnwings7l forming part of 'this specification, Figure l is e seotionel view of o valve embodying my invention. :2 is e seetionel View on the line :l1-a2 of Fig. 4l.

3 illustrates modi-` fied construction.

In the drawing", 2 represents e valve ossing, end 3 e, velvehonnet'thet is removably vmounted in the' 'top oi' the valve Gesine.

The-bonnet 3 has e flange at its lower end inclosing e Chamber 5. A velve stein 6 eX- tends through the bonnet and through e recess 7 whereine coiled 'spring 8 is er ranged. A follower 9 fits Within the end. of the recess 7 and has e pin l0 slidable in e. slot l1. A oep 12 secured to the valve stern has a. bell hearing 13 on the topof the plug. A bevelaced disk 14 is mounted on the stem 6 and e seat 15 therefor is formed in 'the valve bonnet et the upper end o'tlie ehember. The lower end of the valve stem 6 is threaded to fit into en' interiorly threaded sleeve 16 mounted on the valve disk l?, seid sleeve being adapted to slide in the chamber 5 and prevented from rotating therein by e, pin. 18 fitting Within e vertical slot 19in seid sleeve. The disk 17 hes e, beveled opper' fece 2O to engage a, seat 2l on the lower/end 1 .l l ,1 1 w' of the bange i so that Ween the niek is raised tothe limit oi yits upward movement the entrance to the chamber 5 will be closed. and the' valve adapted' for 'use on vacuum sys'oems Where the -suetion might compress Lthe stem spring and permit entrance oi' air around the valve stein. A seat 21 is provided in the valve easing for-.the disk 17 end e flange 22 surrounds the said seat and is provided with e series of comparatively smell perforetions 23. .This flange prevents sediment' frein 'the radiators lodging on the valve seet while allowing Water to flew freely-through the valve, -ilt will he understood that when 'the valve stem is turned the disk l? will be' raised or lowered to open or close the valve. Rotary movement o'l the dislr will be prevented by the pin i8 and A the stern is revolved the disk will be raised or lowered. Tlie disk le contacting with its seat in the bonnet will prevent the escape of steam or Water from the valve, and being held by the spring device on its seet will dispense with the usuel peeking required around the stem,

in Fig. 3 o modification is shown which consists 1n provi Qing e. sleeve 16 that is reotenguler in cross section to lit e Correspond ingly shaped soelret in the veive honnet end dispensing with 'the Groove :ind guiding pin.

in platee of the integral iienge 22 on the seat or the ve-ive l nsy provide e well eonsisting of iine wire ymesh 'having solisten tielly the seine llnetione the flange .2 with the series oi perioietions.

A velveeornprising easing having e ring removably rrnnged therein7 the top of seid ring having e. vertieelllenge formed thereon end provided With e. series of per* fretions which ere ltoo smell to allow pas of sediment from the radiators onto the valve seet but allow the free passage of writer therethrough end the upper portion or. said ring inelosed by seid iienge lie-ving a beveled valve seat end e. valve dish. adopted to fit within seid 'Flange und Contact with seid seat end e stern eonneeted with seid disk.
